Playing his fifth Grand Slam tournament at the 1974 French Open, the much touted Bjorn Borg made his breakthrough as the first teenager in the Open Era to win a Major.

A year on after losing to Adriano Panatta in the fourth round on his Grand Slam debut at this very tournament, Borg returned to the fourth round for the loss of just one set. In his first stern test, the 17-year-old prodigious Swede lost the opening set without winning a game before overcoming American Erik van Dillen in five sets.

The going would only get tougher for the teenager as he would need to claw back from a two sets to one deficit to down Mexico's Raul Ramirez, before requiring four sets against Harold Solomon in the semifinals.

Borg's toughest test came in the final against Spain's Manuel Orantes, who seemingly had a stranglehold of the contest by taking a two set lead. But one set away from his first Major title, the Spaniard would spectacularly fall apart as Borg conceded only two games in three sets to become the first teenager in the Open Era to win a Grand Slam title.

Borg would return the next year to successfully defend his title, becoming the first teenager to win multiple Grand Slam titles, and one of only three players in the Open Era to accomplish the feat.
